AI FAE Platform3. Documentation and Tool Navigation
This chapter collects the official documents, evaluation board materials, SDK and development support packages for the N32G41x series. The document names, versions and purposes are taken from the NSING Technology series page, model pages and download centre. Only materials whose names and versions have been checked are listed; the download centre requires a member account.

The applications/BOOT_As_ExtFLASH project demonstrates the write-protection check and programming of the BOOT area; read it alongside the application note on using the BOOT area as extended FLASH.
3.2 Evaluation Boards
| Board | Typical materials | Where to obtain it |
|---|---|---|
| N32G412CBL7_STB | Hardware user guide: schematic and usage instructions of the minimum system board | Download centre: hardware |
| N32G412RBL7_STB | Hardware user guide: schematic and usage instructions of the minimum system board | Download centre: hardware |
| N32G415CBL7_STB | Hardware user guide: schematic and usage instructions of the minimum system board | Download centre: hardware |
| N32G415RBL7_STB | Hardware user guide: schematic and usage instructions of the minimum system board | Download centre: hardware |
The boards can be requested or purchased from the Buy samples page. The board resources used by the SDK examples are defined in projects/n32g41x_EVAL/bsp/inc/n32g41x_stb.h and bsp/src/log.c:
| Resource | Pin | Definition |
|---|---|---|
| LED1 / LED2 / LED3 | PA1 / PA7 / PB1 | LEDx_ON_STATE is Bit_SET: the LED lights when the pin outputs a high level |
| KEY1 / KEY2 / KEY3 | PA4 / PA5 / PA6 | Pull-up input; the pressed level is Bit_RESET |
| WKUP key | PA0 | Pull-down input; the pressed level is Bit_SET |
| Log UART | PA9 (TX) / PA10 (RX) | USART1, 115200 bps, 8 data bits, 1 stop bit, no parity |
The board header file defines pin macros only and does not distinguish between board models. Before connecting external devices or changing boards, check the pins against the hardware user guide of the board in use.
3.3 SDK and Development Support Packages
| Document | Purpose | Where to obtain it |
|---|---|---|
| N32G412 series software development kit / N32G415 series software development kit | Firmware drivers, startup files and example projects | Download centre: firmware and software |

The Keil support pack selects the programming algorithm by Flash size: 64 KB models use N32G41x_64.FLM and 128 KB models use N32G41x_128.FLM.
The IAR and J-Link device patch packages are cross-series packages and are not listed on the series page; search for them by name in the download centre. The version in the directory name of the packages shipped with the SDK differs from the version listed on the official site; use the version listed on the official site.
